your psu is a epic win
my god these evga 1500 are expensiveIt is indeed very expensive, I bought it for around £300 in November and I've seen it up to £400 recently.
But it's the best power supply money can buy, it overclocks to 1600W + you can set it to power up your miners with no need for shorting ATX pins.
I would say most miners will be better off with 2 cheaper power supplies instead of this one (it'll cost much less) but in my case once I'm done with mining I can always use it to build a PC with it.
I also have two of those 1500W supplies, and they are kick ass! Single/multi rail in one, load meter, nice quality cabling... I like using them to measure wattage draws on cards in real time, then I'll swap over to smaller PSUs when I feel everything is in safe running conditions. My only complaint is it's loud and you can hear the APFC clicks a lot when running 1200W of water cooled GPUs. Loudest thing in the build, by far
Are you running all 6 of those 280x's on one. I know it'll do it on 220, but I never really thought it would run all 6 at full throttle.
